Abstract
A key structure includes a base plate, a supporting element, a resilience arm and a keycap. The keycap includes a bulge. The supporting element is installed on the base plate. The resilience arm is connected with the supporting element and aligned with the bulge of the keycap. The keycap is connected with the supporting element. When the keycap is moved toward the base plate, the bulge is moved downwardly to push the resilience arm. After the resilience arm is pushed by the bulge, the resilience arm is subjected to elastic deformation and separated from the bulge. After the resilience arm is separated from the bulge, the resilience arm knocks on the keycap, so that a sound is generated.
